How many 24 × 18 × 18 in boxes fit in a 45ft high cube?
24 × 18 × 18 in boxes of 610 × 457 × 457 mm (also called 4.5 cubic foot boxes, large moving boxes) in a 45-foot high-cube container (45HC) — inner dimensions 13,556 × 2,352 × 2,698 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 89% of the space used, 6 layers high, about 9,664 kg (35% of payload). Open this load in the 3D planner →

The answer in detail
The large 4.5 cubic foot moving and shipping box.
An extra 1.5 m of length over a 40HC, popular for European intermodal moves where a 45ft box matches a 13.6 m trailer.
The simple grid estimate is 22 along the length × 5 across × 6 high = 660. The engine found 604 — 54 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used and by choosing the orientation that gives the most layers. The top view above shows the pattern.

Frequently asked
How many 24 × 18 × 18 in boxes fit in a 45ft high cube?
604 24 × 18 × 18 in boxes of 610 × 457 × 457 mm fit in a 45ft high cube (inner dimensions 13,556 × 2,352 × 2,698 mm), boxes may be laid on any side. That uses 89% of the 86.0 m³ available and weighs about 9,664 kg.
What are the inner dimensions of a 45ft high cube?
Typical inner dimensions are 13,556 mm long, 2,352 mm wide and 2,698 mm high (533.7 × 92.6 × 106.2 in), giving 86.0 m³ of space and a rated payload of about 27,600 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 24 × 18 × 18 in boxes weigh?
604 × 16 kg ≈ 9,664 kg, which is 35% of the 27,600 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
